ATC-SIM is a web-based air traffic control (ATC) simulator. it’s all but impossible to play unless you’re a die-hard flight-sim fan or an existing ATC controller looking to improve their skills (let’s hope you really don’t need this!).
You can select the airport, wind & realism levels to suit your fancy. Let’s just say you don’t want me in the control tower (real or otherwise).
If you’re more interested in real flight tracking be sure to check out Track Flight Status.
